You've permanently broken it, it is not recoverable.

Normally you have software on the board you want to protect, and that software would provide alternate means of interaction. Usually this would be a loader which is never erased, but allows for secure updates of other application code.

Perhaps you know someone locally who can remove and replace the STM32 IC on the board?

Clive's answer was clear enough, wasn'it? Check the corresponding RM.

Your board is for the bin now (given that the program present in the flash doesn't suit your needs).
